problem with AWK and floats below 0
Hello. I have a problem with AWK and floats below 0 in a script.
It may be simplified to this line (please, take into account that my "locale" is Spanish, so the system will read "," as decimal separator):

Code:
echo -1,25 2,55745 0,33 ,278 | awk '{print $1+1, $2+1, $3+1, $4+1}'

... getting:
Code:
-0,25 3,55745 1 1

So, what about the third and fourth fields? Why do you think AWK is not reading correctly?

I have tried different options (also with printf options), but I am always at the same point: if the number is 0,xxx AWK will not read the decimal part.
Thank you very much in advance,

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
